The default member access for a class is private, so you can't access pointer outside of the class unless you declare it as public.
class someclass {
public:
somestruct* pointer;
}classpointer*;

to add to the other answer, I assume that point is actually allocated ?
anyway, is it a compilation error or a runtime error ?

Hey-
How does one app go about putting a button on the title bar of another window?
I've seen AOL and WebEx do this?
They place a button, which receives events, and posts a pop-up menu.
Thanks in advance

I have six lines in my code similar to the following:
Biquad[0]->mfVh = pow(10, (0.05*mfGh));
On compiling the program I get the following error:
error c2666: 'pow': 7 overloads have similar conversions.
Could somebody explain to me what this means.
Biquad[i] is an object of cBiquad.
mfVh and mfGh are floats.
I've tried suffixing 10 and 0.05 with f, but that gives me a separate error saying that the use of the suffix there is incorrect.
If you could let me know what I'm doing wrong it would be of great help! Thanks!

I seem to have fixed it by some kind of brute casting technique.
The line now reads:
Biquad[0]->mfVh =
pow((float)10, (float)(0.05*mfGh));
Here's a link to the MSDN document if somebody else has a similar problem
ERROR C2666
Suggestions for more elegant solutions are welcome!

I had the same problem. Are you using VS2003? It doesnt seem to be a problem in vs6
Change your code like this. Its a bit neater
Biquad[0]->mfVh = ::pow(10.0, 0.05*mfGh);

Josh,
Thanks for the tip, and yes, I'm using VS2003. That's a really weird error...digging through the MSDN documentation helped a little and I typecasted everything that could be (even the result, but apparently that wasn't required).
I like your solution better. Could you please explain what the "::" does?
Thanks again!

The :: means "the pow() function from the globalname space". This is redundant if you dont use namespaces, and probably if you do but I like to use it when calling functions from the c library as it makes the code a bit easier to read im my opinion.
Look at the declaration of the pow() template function in math.h if you are still unsure about how to use it

(I have post it on another forum, but I'd like to offer it first to MFC friends, don't call it as cross-post!)
Image copier is the best image tool in the world developed for artists, programmers and normal users, such as company managers, office staffs.
the software contains over 5,000 images (32x32 and 16x16 pixels).
Each image is in six different styles, so totally the software equals to contain over 30,000 images.
Images can be copied to clipboard for pasting by other applications (such as Photo-shop, Corel-draw).
Images also can be saved as files (gif, jpeg, bitmap etc).
All images can be resampled from 1x1 to 96x96 pixels.
Those images are classified as different categories, such as people, animal, system, equipment ...
don't miss it!
You can download from here
Thank you

You can use the Article submission wizard[^] to submit it to the site automatically. As it will appear on the site immediately, please take some time to prepare your article.
If you don't plan on posting full source code, make sure to post in in the "free tools" section. Good luck

Hi,
I have a XML file which needs to be first validated using a DTD and then parsed to get values & properties associated with tags.
I am using Visual Studio's VC++ 6.0 to write my code. Is anyone aware of any reference or tutorial which would help me learn the same.
Thanks You!!
Regards

I use Xerces[^] to do just that. Imho, it's much faster than MSXML.

 The last version I used was much slower than MSXML (some coworkers of mine actually measured). However that was more than 2 years ago and it is quite possible that things are different now.

No  ,
The zip file (free) contanis some examples, include files and .lib files.
Also Apache Xerces is a good alternative.

I was writing a very simple chatapplication, I compiled it with no errors (it was
first about 127 errors) and no warnings. I wanted to run and than suddenly I got that
message:
Debug Assertion Failed!
I thaught that when there is no error occured, my application will work fine.
But in this case , there is this serious error, so I hope somebody is willing
to help me out. I clicked on Debug GO and after clicking on ignore-button
at the "Debug Assertion Failed" message I get on the this-tab the following
text: this CXX0017: Error: symbol "this" not found
On the locals-tab I get the following text:
+ hInstance 0x00000000
+ hPrevInstance 0x816724e4
+ lpCmdLine 0x00540000 ""
nCmdShow 1919251285
So, I really don't know what's going on, this is my first "complex" application
I wrote. And my goal is to make a very simple chat-application, learn from it and
than write an application to control electronic devices via internet with the basic
of my chatapplication.

I hope I informed you well so you wizbrotherz can help me to get a step closer
to the magic world of computerprograms.
Thank you very much!

I thaught that when there is no error occured, my application will work fine
Sorry, but that's so far from the truth. The language rules (which is all the compiler can check) allow many things that are prohibited by the "contract" (that is, how a function is supposed to be used).
No useful programming language can guarantee tzhe program does what you expect, but C++ requires much more discipline, self-control and knowledge than other languages.
Assert's are debug-time checks that verify things that should not happen (like passing a NULL pointer to a function that does not allow NULL pointers)
"this not found" usually means you are currently not in a class' member function.
As much as I'd love to help you, you probably need to start with smaller applications, trying to learn and understand concepts, common tools etc.
I understand the desire for a "real" application, but you need to learn a few fundamentals first. There's nothing magic about things you understand.

hi..
i'm going through hell trying to activate the system speaker. when i try to use the "kernel32" Lib API function "BEEP", i only get a beep in the soundcard's speakers. if they happen to be turned off - i get nothing.
note that:
1) i am using windows 98
2) there is a built-in motherboard system speaker. it's device driver is VMM32.VXD, and the devicer manager says it's functioning properly.
3) the internal speaker itself IS working (it beeps every time i turn the computer on).
4) there is a sound card installed. it's an avance ALS120, and it's driver is ALSWDM.SYS.
if anyone knows anything about this - it doesn't matter if it's in visual C++ or visual basic or whatever, just make the thing beep..
and thanx anyway.
